| In recent decades,China’s social and economic development momentum is rapid,the scale and number of industrial enterprises grow year by year and develop rapidly,the urbanization process is significantly enhanced,the material living standard of the people has been greatly improved,but followed by the continuous decline of atmospheric quality caused by production and business activities.Excessive concentrations of particulate matter and severe smog have a direct impact on people’s lives and health,the contradiction between environmental protection and economic development is becoming more prominent,and there is a big gap between air quality and people’s expectations.Implementing air pollution prevention and control measures,vigorously promoting effective air pollution control,and realizing sustained improvement of air quality have become the aspiration of the people.While vigorously developing social economy,H City has gradually increased investment and paid close attention to environmental governance.After years of tackling air pollution prevention and control,H City has achieved a steady improvement in atmospheric environmental quality.Although the achievements are outstanding,but the current situation of coal siege,key areas of microenvironment remediation is not complete,motor vehicle exhaust pollution,dust pollution and other problems have not been effectively solved,the environmental quality is still in the ranks of cities that do not meet the standards,and the influence of exogenous input is obvious,a little slack,the results of atmospheric governance is easy to rebound.At the same time,H City also has many shortcomings in the process of promoting multi-center treatment of air pollution,which requires continuous exploration,practice and improvement of relevant treatment measures.Based on the theory of polycentric governance,this thesis analyzes the present situation of multi-center treatment of air pollution in H City by literature research,comparative analysis and interview,and clarifies that through unremitting efforts,the air quality of H City can be continuously improved.However,command-and-control policy tools are still dominant,enterprises are passive in fulfilling their responsibilities,social forces are not effective in participating,market operation is not mature,the communication mechanism of multiple subjects is not smooth and the structure is not reasonable,and geographical and climatic factors are obviously affected,and the causes of relevant problems are analyzed.At the same time,based on the experience of Lanzhou and Shenzhen in China as well as the experience of the United States,The United Kingdom and Tokyo in Foreign countries,suggestions for H City to improve the effect of multi-center air pollution control are put forward.In order to avoid "multi-center" into "no-center",China will explore the establishment of a "multi-centralism" governance structure based on China’s national conditions,and give full play to the role of multi-entities.Including the government leading role,compaction enterprise’s main body responsibility,prominent role in promoting social forces,atmospheric governance promote market-oriented operation,to establish "a nuclear multivariate" polycentric governance interactive adjustment mechanism and consummate the prevention and control of atmospheric pollution pattern of horizontal and vertical coordination Suggestions,such as working for the local government to treat gas provide certain reference and reference. |
